I have an '84 Wolfsburg edition Westfalia camper. I believe it to top of the line in that year.
It has a two tone colour scheme, being dark brown lower,kind of beige upper.
Inside, the seats are very plush cloth,with armrests.
The dash is different with a digital clock and a tach.
It also has power steering which other '84 models did not have. It has a/c and rear heater.
All the camping options are included except an add-on awning.
I believe these are the main differences but there may be more.
Mine has been garaged for a lot of its life and has 67k miles with no oil or water leaks and I am thinking of selling it if anybody is interested.
Located in SC.
